Method Detail

generate

void generate(stand st)

generate missing heights. The method works species by species. 1. It checks if there are heights missing (<1.3m). 2. If, yes it counts the number of given heights. If the number of given heights is > 5 then a heightcurve will be calculated and the trees with no height values will get the value from the height curve > 1 then the uniformheight curve will be used to estimate the missing height = 0 no height information of a species, wait until other species are processed 3. If all species are processed check again for species without any information. The missing heights for those species will be generated as described above, but all valid diamter height information will be used. If no height information is given, there will be problem. Additional height information from trees which do not belong to a stand. This happens sometime in growth and yield research. Read in those trees and mark them by giving them the number "nurH". Those trees will be removed by this method after generating heights
